CAR Roon metal carf roofs lwherein vmetal roof sheets `extend from eaves to vridge ofthe car and 1 are connected to the car and to each other at the ridge in a manner adapted to permit each ysheetto slue or oscillate about a point midway of its ridge vendy in accommodatingl itself Vto!v the distortions Vof the car frame; 'y

and it relates particularly` to ridge construction of vroofso'f this type. lbleretofore,.in

vthis type of roof,fit has beenconsidered im# practicable toprovidethesheets with over-v y n Y v Versely of tliecar i'roin Veaves to ridge thereofandY are provided attheirridge ends avith .lapping ridge'seain flanges; and -the'princif- -f -palobject of' the present invention is to pror Vide a simple and e'liicientarrangenient thatj .Will enable sheetsfhaving'overlapped ridge; seam lflaiigesrto pivot-vor oscill'ate around a lregion -iiear the middle kof their ridge ends ,I Whenever there is .movement of said sheets. Another object is toprevent damageto the;l sheets during suchV 'movement Other ob Y y Y y l doubled-.back flanges; that rest f on the .roof sheathing and cooperateavvith doubled-under jects are reduced cost of manufacture.few-l ness of parts and compactness of design.,

` .The invention consistsk principally in al yflexible outside metal vcar Iroot comprising Vroof sheetsthat yextendfrorny eaves to ridge "and have overlapped ridgeseam iangesthat are covered by fixed ridgeseam covers, *the side Walls lof said overlappedridgef seam flanges and `said ridge seam.V coversy beingf normally incontact Witheach other aty their y middle` portions only,.thereby permittingy a limited angular' adjustment' of .j said sheets relative to eachother and to said seam covers i'n response to the Weaving of the car frame.

By

this arrangemen'trtlie ridge seam caps and the overlapped ridge seam'flanges each pair 'of roof sheets have a snug lit neartheir middle portions and are normally spaced Y'apart at their ends, whereby the sheets are force'dto roll or rock about the contact portions' ot their lapped ridge flanges whenever there is movement of 'said sheets. Thus, such lsheets are adapted for limited independent Vsluing movement about the contacting po-rtions of their overlapped'V ridge flanges in accommodating vtheni'selves to the distortionsI of theV car frame. VVIt isfnoted thatthe hereinbefore 'described ridge Vseam construction secures a pivotal or sliiing movement'of sheets whose adjacent marginal portions are provided with hollow ribsV that are lapped to vform vweatlierprooling seams, which .forin of seam is superior'to t-he yseam constructions heretofore required ell) 'for securing such movement of the roof sheets.
